It is necessary to follow the instructions correctly so that everything works perfectly. Without a doubt I would ask for it again and an excellent gift. In principle, the assembly instructions are sufficient, a child could assemble it without problem. Overall, a cool developmental toy. I recommend.

Perfect!!!

It is an awesome spider.

Everything came well packaged, with a content and quality control checklist, as well as an Internet address to download the software. Good quality of material and very good price. ! Excellent! Everything works very well, on the first try. Very complete and detailed information is included in the download. It is easy to translate. Very happy with the purchase!

Very nice little robot. I upgraded with metal gear servos and love it!
